Answer:
the same as the products.
Explanation:
Law of conservation of mass states that the mass of the reactant is always the same as the products since they are not lost nor gained.
Answer:
The answer is the solution containing the 90g of water.
Explanation:
Because both solutions have the same amount of the sodium chloride, the concentration would be the same if they both had the same amount of water.
Because the second solution has less water, there is more of the sodium chloride per each drop of water.
I hope this helps :)
Answer:
See the answer below
Explanation:
A decrease in pressure would see a shift in the equilibrium to the left-hand side of the equation.
<em>According to a particular chemical principle, a system in equilibrium that has one of the constraints affecting reactions applied or removed would experience a change in the equilibrium position so as to annul the effects of the application/removal of the constraint.</em>
In this case, 2 moles of NO2 is present on the left-hand side as opposed to 1 mole of N2O4 on the right-hand side. A decrease in pressure will create more space for the formation of NO2 on the left-hand side. Thus, the equilibrium will shift a bit to this side so as to annul the effects of the decrease in pressure.
I think it is B
Hope my answer help you?!?!?!?!?
Answer: 112.2 g
Explanation:
The atomic mass of silicon is 32.065 g/mol, so 3.5 moles have a mass of (3.5)(32.065) grams, or about <u>112.2 g</u>
